[Right ventricular cavernous hemangioma: a rare cardiac primary neoplasia].

: Primary neoplasia of the heart is rare and often diagnosed postmortem (with a prevalence < 0.2% at postmortem examinations) due to the lack of specific clinical symptoms and signs. Among benign cardiac tumors, cavernous hemangioma has a prevalence of 2.8%. Less invasive diagnostic techniques such as transthoracic echocardiography allow for the diagnosis to be made during life with definitive surgical treatment. We report a representative case of right ventricular cavernous hemangioma, which mimicked right ventricular failure associated with systolic pulmonary flow tract obstruction. Surgical treatment was indicated for symptom severity and for the unpredictable behavior of the large neoplasm.
